Complete Copper Molybdenum Flotation India
Nature of the porphyry copper deposit, consisting mainly of copper and molybdenum ore, of which the copper-based, this copper and molybdenum deposit is the main source of ore. Mineral processing equipment in the plant selection based on copper or copper-molybdenum molybdenum obtained mixed powder.
Copper Molybdenum Processing Plant
Flotation of the ore minerals due to the optional study of copper and molybdenum minerals disseminated fine-grained, the grain size of chalcopyrite 0.074mm share of 37.16%, while the share of molybdenite only 1.00% In addition, the ore contains trace amounts of carbonaceous, which is to obtain high-grade molybdenum concentrate very negative result, for the ore characteristics, comparative study of methods, optimizing the process, the small pilot study to obtain the following research results:
● Select the copper-molybdenum thick, through the grinding fineness, collector dosage and the type and amount of lime comparison test to determine the best period of grinding fineness of 65% for the-0.07mm, collector agent Z-200 the amount of sulfur ammonia fat 22.5gt, lime dosage 1000gt won 87.63% of copper recovery
● Select the copper molybdenum, by contrast test conditions selected, and then pulverized to determine the degree-0.045mm accounted for 80%, the best grade of copper reached 23.32%
Copper Molybdenum Mining Equipment
● In the copper-molybdenum separation, and then finely ground by degrees, the amount of sodium sulfide and sodium silicate dosage comparison test, and then pulverized to determine the best degree-0.045mm (88%), sodium sulfide dosage of 300gt, water Glass dosage 40gt, received a grade of copper ore index is 25.64%, 92.02% operating rate was 3.29% molybdenum grade is, the operating rate was 85.19%
● Copper-molybdenum separation open trial studies have shown that the main impact of molybdenum concentrate grade is gangue minerals, quartz, 20% carbon mass accounted for 15% to 20%
● Using lignin, CMC carboxymethyl cellulose and potassium permanganate on carbon molybdenum de-de-carbon results show that the above agents for the improvement of quality molybdenum concentrate has little effect.
● Combined with the analysis of experimental data and the considerations, and ultimately determine a reasonable process that uses a copper-molybdenum roughing grinding, a roughing and two copper-molybdenum election sweep the election and then using a mill and two Selected copper-molybdenum separation times using three re-grinding, a separation, eight and two scavenging the final selection of a grade of 37.19% gain, recovery of 62.37% of the molybdenum concentrate grade of 23.76% and the recovery of 89.99% of the copper concentrate
Copper-molybdenum Ore Flotation Process Superiority
● beneficiation process: porphyry copper after crusher and ball grinding mill after the crushing of coarse concentrate regrinding re-election, under the conditions in the coarse copper-molybdenum mixed roughing, from crude concentrate regrinding re-election to elect The copper-molybdenum ore grade will improve a lot.
● flotation ph: molybdenum content is too low, generally copper-molybdenum flotation, flotation of molybdenite best ph value of 8.5, generally contain pyrite ores, so inhibition of pyrite, ph value can be adjusted within the range of 8.5-12.
● Flotation agents: used to do the copper-molybdenum mixed xanthate collector election. Auxiliary collector black medicine, z-200, kerosene, etc. When using kerosene, with particular attention to the proportion of foaming agent to maintain the best state of the bubble, blister agent over the major alcohol with pine oil.
